A seat assembly may include a seat, a first bladder assembly connected to the seat, a second bladder assembly connected to the seat, and/or an electrical control unit (ECU) configured to independently control the first bladder assembly and the second bladder assembly. The ECU may be configured to maintain a level of inflation of the first bladder assembly to provide a hugging effect to a user of the seat while inflating and deflating the second bladder assembly to guide breathing of said user.

A fully adjustable privacy/protective headrest with foldable protective wings for use in connection with furniture and with passenger vehicles such as aircraft, trains, and buses.

In embodiments, an aircraft passenger seat assembly includes a seatback assembly including one or more lateral seatback sections. In embodiments, at least one lateral seatback section includes a base seatback panel coupled to a seatback frame, a first set of segmented seatback panels coupled to the base seatback panel, and a second set of segmented seatback panels coupled to the first set of segmented seatback panels. In embodiments, the aircraft passenger seat assembly further includes a plurality of actuatable assemblies, wherein the plurality of actuatable assemblies include a first set of actuatable assemblies configured to selectively actuate the first set of segmented seatback panels relative to the base seatback panel, and a second set of actuatable assemblies configured to selectively actuate the second set of segmented seatback panels relative to the first set of segmented seatback panels.

The present disclosure discloses a seat back assembly including a backrest, a headrest and a side wing. The headrest is slidably installed at an upper end of the backrest, and the side wing is disposed on a side of the backrest and is capable of folding and unfolding relative to the backrest. The seat back assembly further includes a driving member, which is disposed on the backrest or the headrest and moves along with the headrest relative to the backrest. The headrest at least, relative to the backrest, has an initial position close to the backrest and an operation position driving the side wing to unfold relative to the backrest. The side wing is folded on the backrest when the headrest slides to a position between the initial position and the operation position.

Provided is a vehicle seat device that includes a headrest to support a head of an occupant seated on a vehicle seat. The vehicle seat device includes a rest operation adjustment mechanism provided on the headrest and to restrict or allow movement of the head of the occupant seated on the vehicle seat and a controller that controls the rest operation adjustment mechanism to allow the movement of the head of the occupant when a frequency of a vibration in a width direction of a vehicle is equal to or larger than a predetermined value.

To provide a vehicle seat in which the posture of the head of the occupant is controlled with a simpler configuration to reduce motion sickness of the occupant, the vehicle seat includes: a seat cushion; a seat back; a headrest including a main part configured to support the back of the head of the occupant, a left side part connected to a left edge of the main part to be rotatable about a vertical axis, a right side part connected to a right edge of the main part to be rotatable about a vertical axis, a left drive device for rotating the left side part forward relative to the main part, and a right drive device for rotating the right side part forward relative to the main part; an acceleration acquisition device; and a control device which, when a rightward acceleration is acquired by the acceleration acquisition device, makes the right drive device rotate the right side part forward until the right side part is positioned on a right side of the head of the occupant, and when a leftward acceleration is acquired by the acceleration acquisition device, makes the left drive device rotate the left side part forward until the left side part is positioned on a left side of the head of the occupant.
